Driver distraction
A driver has a responsibility to do everything
possible to ensure his or her own safety and
the safety of passengers in the vehicle and oth-
ers sharing the roadway. Avoiding distractions
is part of that responsibility.
Driver distraction results from driver activities
that are not directly related to controlling the
vehicle in the driving environment. Your new
Volvo is, or can be, equipped with many fea-
ture-rich entertainment and communication
systems. These include hands-free cellular tel-
ephones, navigation systems, and multipur-
pose audio systems. You may also own other
portable electronic devices for your own con-
venience. When used properly and safely, they
enrich the driving experience. Improperly used,
any of these could cause a distraction.
For all of these systems, we want to provide the
following warning that reflects the strong Volvo
concern for your safety. Never use these devi-
ces or any feature of your vehicle in a way that
distracts you from the task of driving safely.
Distraction can lead to a serious accident. In
addition to this general warning, we offer the
following guidance regarding specific newer
features that may be found in your vehicle:
•Never use a hand-held cellular telephone
while driving. Some jurisdictions prohibitcellular telephone use by a driver while the
vehicle is moving.
•If your vehicle is equipped with a naviga-
tion system, set and make changes to your
travel itinerary only with the vehicle parked.
•Never program your audio system while
the vehicle is moving. Program radio pre-
sets with the vehicle parked, and use your
programmed presets to make radio use
quicker and simpler.
•Never use portable computers or personal
digital assistants while the vehicle is mov-
ing.
Accessory installation
•We strongly recommend that Volvo owners
install only genuine, Volvo-approved
accessories, and that accessory installa-
tions be performed only by a trained and
qualified Volvo service technician.
•Genuine Volvo accessories are tested to
ensure compatibility with the performance,
safety, and emission systems in your vehi-
cle. Additionally, a trained and qualified
Volvo service technician knows where
accessories may and may not be safely
installed in your Volvo. In all cases, please
consult a trained and qualified Volvo serv-
ice technician before installing any acces-
sory in or on your vehicle.
•Accessories that have not been approved
by Volvo may or may not be specifically
tested for compatibility with your vehicle.
Additionally, an inexperienced installer
may not be familiar with some of your car's
systems.
•Any of your car's performance and safety
systems could be adversely affected if you
install accessories that Volvo has not tes-
ted, or if you allow accessories to be instal-
led by someone unfamiliar with your vehi-
cle.
•Damage caused by unapproved or
improperly installed accessories may not
be covered by your new vehicle warranty.
See your Warranty and Service Records
Information booklet for more warranty
information. Volvo assumes no responsi-
bility for death, injury, or expenses that
may result from the installation of non-gen-
uine accessories.

Rear fog lightThis light indicates that the fog
light is on.
CHECK ENGINE Malfunction indicator
light
On-Board Diagnostics II (OBDII): As you drive,
a computer called "OBDII" monitors your vehi-
cle's engine, transmission, electrical and emis-
sion systems. The CHECK ENGINE light will
light up if the computer senses a condition that
potentially may need correcting. When this
happens, please have your vehicle checked by
a trained and qualified Volvo service technician
as soon as possible.
A CHECK ENGINE light may have many cau-
ses. Sometimes, you may not notice a change
in your vehicle's behavior. Even so, an uncor-
rected condition could hurt fuel economy,
emission cleanliness, and driveability.
Extended driving without correcting the cause
could even damage other components in your
vehicle.
Canadian models are equipped
with this symbol for the Malfunc-
tion Indicator Light.
ABS (Anti-lock brake system)If the warning light comes on, there
is a malfunction of the ABS system
(the standard braking system will
still function). The vehicle should
be driven to a trained and qualified
Volvo service technician for inspection. See
page 153 for additional information.

All Wheel Drive (AWD) – general
information
Your Volvo can be equipped with an electron-
ically controlled All Wheel Drive system*, which
means that power is distributed automatically
between the front and rear wheels. Under nor-
mal driving conditions, most of the engine's
power is directed to the front wheels. However,
if there is any tendency for the front wheels to
spin, an electronically controlled coupling dis-
tributes power to the wheels that have the best
traction.
Tire dimensionsVolvo recommends that you always drive on
tires of the same brand, size, construction
(radial), tread pattern, load-, speed-, traction-,
temperature-, and treadwear rating. Never
drive on mixed tires, except for brief periods
when the temporary spare tire is in use.
Always use properly inflated tires of correct
dimensions. Tire size and inflation pressures
are shown on the tire inflation pressure plac-
ards, located on the driver's side B-pillar (the
structural member at the side of the vehicle, at
the rear of the driver's door opening), or on the
inside of the fuel filler door on Canadian mod-
els.
Temporary SpareThe temporary spare tire is for temporary, low-
speed, short-distance use only. Replace it with
a full-sized tire as soon as possible. Do not
drive on the temporary spare at speeds above
50 m.p.h. (80 km/h).
NOTE
Never install snow chains on a temporary
spare.

06 Starting and driving
Stability system

157 Dynamic Stability Traction Control
(DSTC)
The stability system consists of a number of
functions designed help reduce wheel spin,
counteract skidding, and to generally help
improve directional stability.
NOTE
A pulsating sound will be audible when the
system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel
spin by transferring power from a drive wheel
that begins to lose traction to the wheel on the
opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of DSTC's permanent functions and
cannot be switched off.
Spin control (SC)The spin control function is designed to help
prevent the drive wheels from spinning while
the vehicle is accelerating.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily switch off this function for maxi-
mum tractive force.
Temporarily switching off Spin control1. Turn the thumbwheel (1) on the left-side
steering wheel lever until the DSTC menu
is displayed.
2.
Hold down the RESET button (2) to toggle
between
DSTC ON or DSTC SPIN
CONTROL OFF.
NOTE
•The message DSTC SPIN CONTROL
OFF indicates that the stability sys-
tem's spin control function has tempo-
rarily been switched off.
•The stability control indicator light will
illuminate and remain on until spin con-
trol has been reactivated.
•The spin control function is automati-
cally enabled each time the engine is
started.
•DSTC ON indicates that all system
functions are active.
Active Yaw Control (AYC)This function helps maintain directional stabil-
ity, for example when cornering, by braking
one or more of the wheels if the vehicle shows
a tendency to skid or slide laterally.
This is one of DSTC's permanent functions and
cannot be switched off.
WARNING
The car's handling and stability characteris-
tics will be altered if the DSTC system func-
tions have been disabled.

and responsibility when operating the vehi-
cle. Speed and driving style should always
be adapted to traffic and road conditions.

07 Wheels and tires
Uniform Tire Quality Grading

186
ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY
REQUIREMENTS IN ADDITION TO THESE
GRADES
Quality grades can be found, where appli-
cable, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire gra-
ded 150 would wear one and one half (1 1/2)
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and many depart signifi-
cantly from the norm due to variation in driving
habits, maintenance practices and differences
in road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING
The traction grade assigned to this tire is
based on braking (straight-ahead) traction
tests and is not a measure of cornering
(turning) traction.
TEMPERATUREThe temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a minimum level of performance that all pas-
senger vehicle tires must meet under the Fed-
eral Motor Safety Standard No. 109. Grades B
and A represent higher levels of performance
on the laboratory test wheel than the minimum
required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-
inflation, or excessive loading, either sepa-
rately or in combination, can cause heat
buildup and tire failure.
